freakonomics

What's more dangerous: a gun or a swimming pool?
What do a schoolteacher and a sumo wrestler have in common?
Why do drug dealers still live with their mothers?
How are the Ku Klux Klan and real estate agents similar?
Perhaps these are not the typical questions an economics expert asks themselves, but Steven D. Levitt and Stephen J. Dubner are not typical economists.
They are specialists who study the essence and enigmas of everyday life, and whose conclusions often turn conventional wisdom upside down.
Through practical examples and sarcastic insight, Levitt and Dubner demonstrate that economics, at its core, represents the study of incentives: how people get what they want or need, especially when other people want or need the same thing.
